Siemens SIRIUS 3RT2015-1BB41-1AA0 Power Contactor, 7A, 3 kW, 400V, 24V DC Coil, Size S00 Original Brand New

Overview: SIRIUS 3RT20 Power Contactor

The Siemens 3RT2015-1BB41-1AA0 is a highly efficient and compact power contactor from the SIRIUS 3RT20 series, engineered for switching motors and other loads up to $7\text{A}$ and $3\text{kW}$ at $400\text{V}$ (AC-3/AC-3e).

This 3-pole contactor features a low-power $24\text{V DC}$ control coil for direct integration into low-voltage control systems and PLC applications. It includes one integrated Normally Open ($1\text{NO}$) auxiliary contact for easy control circuit feedback and signaling. The device utilizes robust screw terminals for secure, reliable wiring and is designed for space-saving upright mounting (Size S00) on a DIN rail, making it ideal for modern industrial control panels.
